Description FLI8668

1 Description

The FLI8668 offers high integration for advanced, dual-channel applications of Picture-in­Picture (PIP) and Picture-by-Picture (PBP). Two video decoders with 3D comb filters and
two channels of DCDi processing, and true 10-bit performance provide the highest quality
picture for a two-channel application.

Special performance features such as the Faroudja DCDi Cinema video format converter,
blue stretch, DDR memory with a read-write of 10 bits per pixel, and flexible sharpening
algorithms provide unparalleled performance. The video quality level that was exclusive to
Faroudja Home Theater Systems is now available in a single-chip solution.

The FLI8668 also comprises an integrated Analog Front-End (AFE) that includes two triple
ADCs, a cross-point switch, and two Faroudja Intellicomb™ 3D comb filters. The flexible
AFE ensures simple PCB design with direct connections to TV tuners and input video
connectors. Thus, the FLI8668, for a single LCD TV chassis, is able to support worldwide
standards. For regional variations, only a connector and firmware change are required.

The integrated VBI dataslicer and decoder eliminate the need for external components
resulting in significant cost reduction. The FLI8668 supports many worldwide VBI standards
for applications of Teletext, Closed Captioning, V-Chip, and other VBI services.

An embedded microprocessor and a versatile OSD in a single device will facilitate rapid
development of a reliable and attractive product. The FLI8668 utilizes the common Cortez
family firmware making migration easy and effortless across different hardware platforms
within this family.
